What is tendinitis?
Degenerative tears to the tendons, including fibroblasts and microfibroblasts, cause an inflammation of the tendon area. The over-stretching and close-to tearing causes the pain in the particular area.

So how do I prevent it?
1. Make sure you stretch before you workout; stretching warms the muscles and helps you to smooth transition into your workout.
2. Gradually lead into your workout; putting to much stress on cold muscles can cause uncomfortable workouts.
3. Know your boundaries; know the difference between a "good" pain and a "bad" pain.
4. Wear properly fitting shoes; if your shoes fit and support you properly, you should have an easier time working out and a better support for your muscles.
